ALPINE B. ROSSON, OF LINCOLN, ARKANSAS.

HAMMER.

Application filed June 9, 1925. Serial No. 35,993.

My present invention has reference to a tool construct-ion.

My object is to provide a means for easily,

quickly and securely attaching a handle to a tool head, such for instance as a hammer.

A further object is the provision of a handle for such tools that can be effectively gripped by the operator.

Other objects and advantages will present themselves as the nature of the invention is better understood, reference being had to the drawings which accompany and form part of this .application.

In the drawings:

Figure 1 is a side elevation of a tool in accordance with this invention.

Figure 2 is a sectional view approximately on the line 22 of Figure 1.

' Figure 3 is a sectionalview on the line 3-3 of Figure 1.

Figure 4 is an inverted plan view of the tool head and atop plan View of the handle to be associated with the head.

Figure 5 is a side elevation of a modifica tion.

Figure 6 is a perspective view of the shank employed in the construction illustrated in Figure 5.

My improvement is primarily devised for though, of course, other headed tools may be utilized.

Referring now to the drawings in detail and Figures 1 to 4 in particular, a hammer head of the claw type is indicated by the numeral 1. The head 1, on its under face, is formed with a transverse wedge shaped groove 2, and the side walls provided by the groove are beveled inwardly, as at 3. The handle is broadly indicated by the numeral 4, and is of metal. The handle has one end thickened and provided with a centrally arranged transversely extending wedge tongue 5 whose side walls are beveled inwardly. The tongue 5 is designed to be received in the groove 2 of the hammer head and thereafter there is passed through aligning opnings in the said head and handle a headed bolt member 6. The opening in the handle is threaded to receive the shank of a screw 6 therein. By this arrangement it will be noted that the handle may be easily,

use in connection with hammer heads, al-

quickly and securely attached to the hammer head, 1. p

From its enlarged inner end 7, the shank portion of the handle is hollow and the side walls provided thereby are inclined outwardly. These walls 8 merge into a shoulder 9 and from the shoulder there is extended parallel longitudinally arranged spaced bars 10. The bars 10 have their outer ends connected by a flange 11. All of the bars have their outer portions rounded in plan so that no abrupt sharp surfaces will be contacted by the hand of the user of the tool. Because of the spaced bars 10 the flesh of the users hand will be depressed between said bars with the result that a better grip can be obtained on the handle than those of the ordinary construction. 7

In Figures 5 and 6 the head 12 is provided with a wedge groove to receive the wedge tongue 13 on a metal shank 1a, a bolt 15 holds the head on the shank. The shank has its outer end bifurcated and the inner walls provided thereby are inclined. The arms provided by the bifurcation are indicated by the numeral 15 and between these arms there is arranged a wedge 16 on a handle 17. The handle is secured between the arms by means 18.

The simplicity of my construction and the advantages will'be perfectly apparent to those skilled inthe art to'which such invention relates.

Having described the invention, I claim A device of the character described including a handle having an enlarged inner end, a transversely extending wedge tongue formed at the extremity of said inner end, a tool head having transversely wedge-shaped grooves with their side walls beveled inwardly and adapted to receive therein the wedge shaped tongue on the handle, said enlarged inner end having a threaded bore centrally thereof and extending longitudially the head having an opening aligning with the bore and a threaded bolt passed through the tool head and threaded into the bore of the handle for retaining said tool head against movement relative to the handle.

I In testimony whereof I my signature.

ALPINE B. ROSSON.
